Crownline 315 SCR 2008 vs Crownline 340 CR 2007 — Same Brand, Different Boat

The Crownline 315 SCR 2008 vs Crownline 340 CR 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 850 hp, the Crownline 340 CR 2007 has a 100-hp advantage over the Crownline 315 SCR 2008's 750-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crownline 340 CR 2007 carries 193 gallons versus 139 gallons in the Crownline 315 SCR 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Crownline 340 CR 2007 is rated for 10 passengers, while the Crownline 315 SCR 2008 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 340 CR 2007 could be the deciding factor.

Bottom line: Choose the Crownline 340 CR 2007 if your priority is putting more people on the water — it handles 10 passengers and at 36,0 ft it has the deck room to back that rating up comfortably. The Crownline 315 SCR 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Crownline 315 SCR 2008 vs Crownline 340 CR 2007 — Common Questions

Which is the larger boat — the Crownline 315 SCR 2008 or the Crownline 340 CR 2007?
The Crownline 340 CR 2007 is the longer of the two at 36,0 feet overall. The Crownline 315 SCR 2008 comes in at 32,0 feet, making it roughly 4,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Crownline 340 CR 2007 is rated to a maximum of 850 hp, giving it the larger power ceiling. The Crownline 315 SCR 2008 tops out at 750 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Crownline 315 SCR 2008 is Coast Guard rated for 9 passengers, while the Crownline 340 CR 2007 is certified for 10. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Crownline 315 SCR 2008 measures 116" wide, compared to 14" for the Crownline 340 CR 2007. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Crownline 315 SCR 2008 or the Crownline 340 CR 2007?
The Crownline 340 CR 2007 has the bigger tank at 193 gallons, versus 139 gallons on the Crownline 315 SCR 2008. That 54-gallon difference translates to roughly 162–270 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crownline 315 SCR 2008 and Crownline 340 CR 2007 from the same manufacturer?
Yes — both the Crownline 315 SCR 2008 and the Crownline 340 CR 2007 are built by Crownline. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
